i use sudo ArduCopter-quad -A udp:ip:14550 -C /dev/tty/AMA0
If i am correct at this point i have my 2nd telemetry going out of serial port on navio. Now, i need 115k for Alexmos gimbal, my question is, how do i recognize wich serial is the correct one? (serial1, serial2 ecc ecc) so that i can set the correct 115k baudrate and correct mavlink protocol in mission planner?
i never tried using uart for gimbal; (though pointing secondary telemetry [-c] to the gimbal does not sound right)
uart may work too with navio2 (although NOT with -C option) but i never had a chance to try that
you either use “pass through” for the appropiate channels (something between ch9-ch14) or you set up channels with mnt options from ardupilot (Complete Parameter List — Copter documentation)
Since firmware 2.60 alexmos supports mavlink, so theoretically the gimbal is feeded with ahrs, gps, compass, rc and and some other stuff trough mavlink. So, reading from the manual what i need is a serial on navio with mavlink getting out of it at 115k. What i am wondering is, if i use switch -C, how do i know wich serial i am using serial1…5?
Once i know the serial i can try to double chack again if everything is ok.
